The first opening 75 is formed in a rectangular shape so as to overlap the internal exhaust port 56 when viewed from the front. The opening edge of the first opening 75 is in close contact with the front surface of the casing 52 over the entire circumference via a rectangular annular sealing member 73 arranged so as to surround the entire internal exhaust port 56 .

The guide portion 82 forms an air guide space S3 communicating with the first opening 75 between the guide portion 82 and the base plate 81. The guide portion 82 includes a guide plate 83 that is partially spaced apart from the base plate 81 and is arranged to overlap the first opening 75 when viewed from the front, and a connecting plate 85 that connects the guide plate 83 and the base plate 81.

The guide plate 83 is formed into a rectangular plate shape. The guide plate 83 defines a wind guide space S3 from the front. The guide plate 83 includes an upper edge 83a that extends in the left-right direction and is connected to the base plate 81 above the first opening 75, and a lower edge 83b that extends in the left-right direction in front of and below the upper edge 83a. The lower edge 83b is provided below the first opening 75 when viewed from the front. Thereby, the guide plate 83 is arranged so that the distance from the base plate 81 in the front-rear direction gradually increases as it goes downward. The gap between the lower edge 83b of the guide plate 83 and the base plate 81 is a second opening 76 that communicates the air guide space S3 with the lower space S2.

An exhaust hole 84 is formed in the guide plate 83. The exhaust hole 84 passes through the guide plate 83. The exhaust hole 84 is formed in the center of the guide plate 83 in the left-right direction. The exhaust hole 84 has an overall rectangular shape when viewed from the front, and passes through the guide plate 83 in a mesh shape, for example.

The connecting plate 85 connects the left and right side edges of the guide plate 83 to the base plate 81. The connecting plate 85 has front and back surfaces facing in the left-right direction. The connecting plate 85 extends rearward from the side edge of the guide plate 83 and is coupled to the base plate 81 . A third opening 77 is formed in each connection plate 85. The third opening 77 penetrates the connection plate 85 in the left-right direction. The third opening 77 is provided independently of the second opening 76. The third opening 77 connects the air guide space S3 and the lower space S2. The third opening 77 is formed in the entire upper half of the connection plate 85. In other words, the connecting plate 85 extends rearward only from the lower end of the side edge of the guide plate 83.

The subduct 87 is formed into a cylindrical shape and is connected to the guide plate 83. The subduct 87 is formed into a square tube shape. The opening edge of the first end 87a of the subduct 87 is coupled to the front surface of the guide plate 83. The first end 87a of the subduct 87 is coupled to the guide plate 83 so as to surround only a portion of the exhaust hole 84 of the guide plate 83. In the illustrated example, the first end 87a of the subduct 87 surrounds only the upper half of the exhaust hole 84. As a result, the lower half of the air exhaust hole 84 forms a fourth opening 78 that communicates the air guide space S3 with the lower space S2. The fourth opening 78 opens toward the second slot 40 from the top. The subduct 87 extends forward and upward from the guide plate 83. The subduct 87 extends upward relative to the normal direction of the front surface of the guide plate 83 facing the lower space S2. The opening at the second end 87b of the subduct 87 is a fifth opening 79 that communicates the air guide space S3 with the lower space S2 via the internal space of the subduct 87 and the exhaust hole 84. The fifth opening 79 opens toward the uppermost slot 40.

The connecting portions 72 are provided on both left and right sides of the exhaust duct main body 71. Each connecting portion 72 projects outward in the left-right direction from the exhaust duct main body 71 when viewed from the front. Each connecting portion 72 extends from the left-right end of the base plate 81 along the outer surface of the casing 52, and then is connected to the opening/closing portion 30 across the flange 52a.

The operation of the exhaust duct 70 will be explained with reference to FIGS. 7 to 9. FIG. 9 is a perspective view of the temperature control device of the embodiment.
The exhaust duct 70 receives the cool air discharged from the internal exhaust port 56 into the air guide space S3 through the first opening 75. A part of the cold air introduced into the air guide space S3 is guided by the guide plate 83, flows forward and downward, and is ejected forward and downward from the second opening 76. For example, it is desirable that the cold air ejected from the second opening 76 be directed toward the slot 40 at the lowest stage.

The remaining part of the cold air introduced into the air guide space S3 is blown out from the left and right pair of third openings 77 to the outside in the left and right direction. The cool air ejected from the third opening 77 is ejected higher than the cool air ejected from the second opening 76. For example, it is desirable that the cold air blown out from the third opening 77 be directed toward the height of the slot 40 in the second stage from the bottom.

The remaining part of the cold air introduced into the air guide space S3 is discharged from the exhaust hole 84 of the guide plate. A portion of the cold air discharged from the exhaust hole 84 is ejected forward from the fourth opening 78. The cool air ejected from the fourth opening 78 is ejected higher than the cool air ejected from the third opening 77. For example, it is desirable that the cold air jetted out from the fourth opening 78 go toward the second slot 40 from the top.

All the remaining cold air discharged from the exhaust hole 84 is guided to the subduct 87 and is ejected forward and upward from the fifth opening 79. The cool air ejected from the fifth opening 79 is ejected higher than the cool air ejected from the fourth opening 78. For example, it is desirable that the cold air blown out from the fifth opening 79 be directed toward the uppermost slot 40 .

According to the present embodiment described above, the slot 40 is arranged on the front surface 13 of the housing 10, and the temperature is adjusted on the surface (rear surface 14) facing in a direction different from the direction in which the front surface 13 faces among the side surfaces of the housing 10. A device 50 is arranged. According to this configuration, since the temperature adjustment device 50 is exposed to the outside of the exchange device 1, the piping of the temperature adjustment device and the duct for outside air arranged inside the housing 10 can be reduced. Therefore, the slot 40 can be easily accessed during maintenance of the slot 40. Therefore, the maintainability of the exchange device 1 can be improved.

Of the side surfaces of the housing 10 , the rear surface 14 on which the temperature control device 50 is disposed is disposed on the opposite side from the front surface 13 . According to this configuration, when the plurality of exchange devices 1 are arranged side by side in the left-right direction, the temperature adjustment device 50 is not arranged between the adjacent casings 10, so the exchange devices 1 can be brought closer to each other. Therefore, space efficiency when installing a plurality of exchange devices 1 can be improved.

The temperature adjustment device 50 is provided in the opening/closing part 30 that opens and closes the internal space of the housing 10. According to this configuration, the temperature adjustment device 50 can be evacuated from the inside of the housing 10 by opening the opening/closing part 30. Therefore, when maintaining the inside of the casing 10, a work space can be provided inside the casing 10 without performing any special work. Therefore, the maintainability of the exchange device 1 can be further improved.

The opening/closing part 30 is provided so as to be rotatable around a rotation axis C extending in the vertical direction. According to this configuration, since the temperature adjustment device 50, which is a heavy object, does not move up and down during the opening/closing operation of the opening/closing portion 30, the workability of the work involving opening/closing the opening/closing portion 30 is improved. By providing this, it is possible to suppress the decrease.

The temperature adjustment device 50 is fixed so as to be supported by the opening/closing section 30. According to this configuration, the temperature adjustment device 50 can be displaced integrally with the opening/closing section 30. Therefore, the above-mentioned effects can be achieved.

The temperature control device 50 has an internal intake port 55 that sucks air in the lower space S2 of the housing 10 into the air conditioner main body 51, and discharges the air that has been heat exchanged inside the air conditioner main body 51 to the lower space S2. and an internal exhaust port 56. If a heat exchanger is simply placed inside the casing 10, only the circulation of air heat exchanged by the heat exchanger through convection is possible, and the temperature inside the casing 10 cannot be effectively adjusted. . According to this embodiment, air can be forcibly circulated inside the housing 10 by the air discharged from the internal exhaust port 56. Therefore, the temperature inside the housing 10 can be effectively controlled.

The temperature adjustment device 50 has an exhaust duct body 71 that guides air exhausted from the internal exhaust port 56. According to this configuration, the air discharged from the internal exhaust port 56 can be discharged into the housing 10 with enhanced directivity. Therefore, a desired circulation path for air can be constructed inside the housing 10, and the temperature inside the housing 10 can be controlled more effectively.

Furthermore, since there is no need to separately provide a device for stirring the air inside the casing 10, increases in component costs and power consumption can be suppressed.

Here, in the slot 40, air exchanges heat with the battery 2, heats up, and moves upward due to convection. Therefore, the higher the slot 40 is placed, the more the relatively high temperature air that has been heat exchanged in the lower slot 40 stays around the slot 40, and the cooling efficiency decreases. In this embodiment, the exhaust duct main body 71 has a fourth opening 78 and a fifth opening 79 that open toward the slot 40 and are arranged at different vertical heights. According to this configuration, the air discharged from the internal exhaust port 56 of the temperature adjustment device 50 is actively supplied to both of the slots 40 arranged at different heights. In this embodiment, air discharged from the internal exhaust port 56 of the temperature control device 50 is actively supplied to both the top slot 40 and the second slot 40 from the top. Therefore, the cooling performance of the batteries 2 in the plurality of slots 40 can be made uniform.

The temperature adjustment device 50 has an intake duct body 61 that guides air taken into the internal intake port 55. According to this configuration, air can be taken in at a desired position inside the housing 10, so a desired circulation path for air can be constructed inside the housing 10, and the temperature inside the housing 10 can be controlled more effectively. It can be adjusted to In particular, in this embodiment, since the intake duct main body 61 is open at the upper part of the lower space S2, hot air accumulated in the upper part of the lower space S2 due to convection can be efficiently sucked into the internal intake port 55. Therefore, the temperature inside the housing 10 can be made uniform, and the operating efficiency (cooling efficiency) of the temperature adjustment device 50 can be improved.

The opening/closing switch 18 is provided close to the clasp of the door handle 16 provided on the opening/closing part 30. According to this configuration, the opening/closing switch 18 can be disposed at a location where the gap between the opening/closing section 30 and the opening edge of the housing body 20 is relatively small when the opening/closing section 30 is closed. Therefore, erroneous detection of the open/close switch 18 when the open/close section 30 is closed can be suppressed, and a switch with a narrow operating range can be applied to the open/close switch 18.

The housing 10 is provided with a fixing part 17 that restricts opening of the opening/closing part 30, in addition to the door handle 16 having a catch that locks the opening/closing part 30 and the housing body 20. According to this configuration, the overall rigidity of the housing 10 can be improved, and earthquake resistance can be improved.

Note that the present invention is not limited to the above-described embodiments described with reference to the drawings, and various modifications can be made within the technical scope thereof.
For example, in the embodiment described above, the exchange device 1 is a charging device that charges the battery 2, but the configuration is not limited to this. For example, the exchange device may be a power supply device that supplies power from the loaded battery 2 to an external device.

In the above embodiment, the temperature adjustment device 50 is arranged on the rear surface 14 of the housing 10, but the structure is not limited to this. The temperature control device may be placed on the left side or right side of the housing. Moreover, the temperature adjustment device does not need to be provided in the opening/closing part, and may be provided, for example, in the side wall of the main body of the casing.

Furthermore, the arrangement of the slots 40 is not limited to the above embodiment. That is, the slots 40 may be arranged in any number of stages, and furthermore, any number of slots 40 may be arranged in the left-right direction in each stage. However, by applying the configuration of the exhaust duct main body 71 of the above embodiment to an exchange device having slots arranged in multiple stages, the above-mentioned effects can be achieved.

In addition, it is possible to appropriately replace the components in the above-described embodiments with well-known components without departing from the spirit of the present invention.
